Because heat exchange effect and the copper of aluminium are very approaching, the processing characteristics of high strength alumin ium alloy, working ability have had very large improvement, so the field of aluminium instead of copper application is more and more extensive.In recent years, at home and abroad in the evolution of domestic air conditioning, refrigerator, air conditioning for automobiles, automobile radiators, many successful experiences, failed lesson, to difficulty and the demand of high-strength aluminum alloy welding, caused various equivalent modifications and enterpriser's attention.Automotive air-conditioning system service condition is severe more than domestic air conditioning, in air conditioning for automobiles, and the employing of the heat exchanger of high-efficiency compact (parallel flow type, stacked); In automotive air-conditioning system, substantially all adopt aluminium from compressor, heat exchanger, valve body to pipeline, this just requires intensity of aluminum alloy enough high, weight is also light, corrosion resistance and good, therefore, for the Welding Problems of the novel aluminum alloy that meets above-mentioned requirements and research and develop, adopt, also become one of restriction novel aluminum alloy material, Novel aluminmm alloy structure application " key technology " simultaneously.In addition, in the time of " pipe-pipe connects " of a large amount of heat exchangers that use aluminium alloy, during due to work, the cold-producing medium of pipeline inside is that " vapour-liquid conversion " occurs " having pressure " in the situation that, therefore, to the particularly higher requirement of " air-tightness " proposition of aluminium alloy brazed seam of aluminium alloy pipeline.Due to existing Al-Si brazing filler metal (as 4047,4043 etc.), although its air-tightness meets the demands, the fusing point of himself higher (577 ℃ of solidus temperatures, liquidus temperature is more than 600 ℃), with 3 be, the fusing point of 6 series high-strength aluminum alloys is very approaching, soldering is very difficult.Although its fusing point of Zn-Al solder can be low to moderate 400 ℃ of left and right (if the solidus temperature of 98Zn-2Al is 381 ℃, liquidus temperature is about 410 ℃), but the air-tightness of Zn-Al solder brazed seam is poor, " slip " in laboratory, just up to 16%, cannot meet the large-scale production requirement of a heat exchanger factory hundreds of thousands every day soldered fitting at all.This invention has the middle temperature almit of high-air-tightness, under this technical background, completes.
Summary of the invention
The object of this invention be to provide a kind of fusing point 480 ℃ ~ 520 ℃ left and right, on high-strength aluminum alloy surface and on copper-aluminium alloy good mechanical properties, the brazed seam air-tightness of wetability, superior permeability, brazed seam good, go for the Novel middle-temperature almit of the welding of multiple grade aluminium alloy aluminium-aluminum pipe line structure part.
For this reason, a kind of Zn-Al solder containing Sr, Si, Ti, Ni, P of this invention, its chemical composition by mass percent is: 0.01% ~ 0.1% Sr, 1.5% ~ 6.5% Si, 0.001% ~ 0.01% Ti, 0.001% ~ 0.01% Ni, 0.0001% ~ 0.001% P, 36.0% ~ 65.0% Zn, the middle temperature almit of what surplus was Al have high-air-tightness, has met above-mentioned requirements.
" thering is the middle temperature almit of high-air-tightness " of the present invention, use commercially available zinc ingot metal, aluminium ingot, metal Ti, industrial silicon, al-sr alloy, nickel-phosphorus alloy, adopt conventional smelting mode by design mix proportioning, when smelting, add through optimizing and screen " coverture " determined or adopt " inert gas " protection to smelt, cast, by extruding, drawing, obtain needed solder wire material again; Or by multiple tracks rolling process, be prepared into the strip of desired thickness, width.Add brazing flux, can be made into " flux-cored wire ".Product of the present invention can coordinate commercially available CsF-AlF
3brazing flux or KF-AlF
3brazing flux, can be used for the soldering of multiple grade aluminium alloy aluminium-constructed of aluminium part.
Although be generally 380 ℃～420 ℃ in order to reach the existing Zn-Al alloy solder fusing point of improvement compared with low melting temperature interval), poor air-tightness; Al-Si brazing filler metal (as 4047,4043 etc.), although its air-tightness is good, but higher (577 ℃ of the solidus temperatures of fusing point, liquidus temperature is more than 600 ℃) a difficult problem, through a large amount of " screening test ", finally determine take Zn-Al solder as matrix, add Sr, Si, Ti, Ni, the P element of the amount of (fitting) in a subtle way, thereby neoteric solder molten temperature region is controlled to 480 ℃～520 ℃ scopes, lower than 80 ℃ of left and right of fusion temperature of Al-Si brazing filler metal, utilize " microalloying " effect of more trace elements, improve the air-tightness of new invention solder.Through " optimizing components " and analysis of experiments, determine the best in quality percentage proportioning of " thering is the middle temperature almit of high-air-tightness ".Adopt oxy-propane flame brazing mode soldering 3003 aluminium-alloy pipes-tubular construction (socket), use " flux-cored wire " or brazing wire to coordinate CsF-AlF
3brazing flux, soldered fitting is through the water pressure test (hydraulic pressure is 18MPa, pressurize 30 minutes), brazed seam is without leakage.Soldered fitting maximum in the water pressure test is born pressure can reach 21 MPa(at aluminum pipe position cracking).
This invention has mainly solved following critical problem:
1) there are some researches show: although the fusing point of Zn-Al alloy is low (generally at 380 ℃～420 ℃, individual other fusing point can reach 450 ℃～460 ℃), but its " air-tightness " is poor, when " aluminum pipe-aluminum pipe " brazing, brazed seam slip is higher, cannot be in heat exchanger sector application.Therefore, utilize " microalloying " effect of Sr, Si, Ti, Ni, P more trace elements, improved the air-tightness of new invention solder.
2) find through 15 groups of approximately 150 alloy formula experimental studies, Sr, Si, Ti, the Ni, the P element that add the amount of (fitting) are in a subtle way improving the bubble-tight while of Zn-Al alloy, also have improve Zn-Al alloy in high-strength aluminum alloy wettability of the surface, infiltrative effect.Simultaneously, by optimizing Sr, Si, Ti, Ni, the content range of P element, the molten temperature region of neoteric solder is controlled to 480 ℃～520 ℃ scopes, lower than 80 ℃ of left and right of fusion temperature of Al-Si brazing filler metal (as 4047, 577 ℃ of the solidus temperatures such as 4043, liquidus temperature is more than 600 ℃), thereby obtain " there is the middle temperature almit of high-air-tightness " (in this, temperature is for 577 ℃～600 ℃ of fusing points of 4047), can realize easily the brazing of " aluminum pipe-aluminum pipe " and there is no aluminium alloy element " burning ", the danger of " subsiding ".Adopt oxy-propane flame brazing mode soldering 3003 aluminium-alloy pipes-tubular construction (socket), use " flux-cored wire " or brazing wire to coordinate CsF-AlF
3brazing flux, soldered fitting is through the water pressure test (hydraulic pressure is 18MPa, pressurize 30 minutes), brazed seam is without leakage.Soldered fitting maximum in the water pressure test is born pressure can reach 21 MPa(at aluminum pipe position cracking).
compared with research in the past, creativeness of the present invention is:
One, found " raising air-tightness " effect of P element.
As everyone knows, in copper alloy, P has deoxidation, if " phosphorized copper " TP1(is referring to http://baike.baidu.com/view/3059316.htm).In " tin-lead solder " old edition national standard, add 0.001% ~ 0.004% P and 0.001% ~ 0.004% Ga, be referred to as " anti-oxidant tin-lead solder " (referring to GB 3131-88 " tin-lead solder " table 6).Through more than 10 years, P has " antioxidation " for after everybody knows in tin-lead solder, lead-free brazing, in new edition (version prevailing for the time being in force) GB/T 3131-2001 " tin-lead solder " table 3, table 4, although also listed two kinds of solders containing P0.001% ~ 0.004% in, no longer indicating has been " anti-oxidant tin-lead solder ".And it is found that, only add merely P, needn't add the Ga element of equivalent simultaneously.But, in the present invention, find, verified adding of P through overtesting, be not deoxidation, oxidation resistant effect, but there is the effect of " raising air-tightness ".
Two, the interpolation scope of verification experimental verification preferred Sr, Si, Ti, Ni, P element.
Research in the past, in the research and development of new metallic material, the interpolation scope of Sr, Si, Ti, Ni, P is generally all very wide in range.This research finds to have the Zn-Al base alloy of good " air-tightness ", good brazing property (as solder wetting, permeability, brazed seam mechanical property), and the addition of Sr can not exceed 0.01% ~ 0.1% scope; The addition of Si can not exceed 1.5% ~ 6.5% scope; The addition of Ti can not exceed 0.001% ~ 0.01% scope; The addition of Ni can not exceed 0.001% ~ 0.01% scope; The addition of P can not exceed 0.0001% ~ 0.001% scope.Special needs to be pointed out is: P adds (as lead-free brazing, tin-lead solder) in solder, mainly to play a part " anti-oxidant ", its addition is that 0.001% ~ 0.004%(is referring to GB/T 3131-2001 " tin-lead solder " table 3), but in the present invention, the addition of P must be controlled at 0.0001% ~ 0.001% scope.
A large amount of tests is found, in Zn-Al base alloy, when adding after the elements such as Sr, Si, Ti, Ni, then adds micro-P, adds 0.0001% ~ 0.001% P, very large to the brazed seam air-tightness effect of raising Zn-Al-Sr-Si-Ti-Ni-P solder.The test data in this laboratory shows, add after P element, the slip of brazed seam 6/100000ths has been dropped to and has added 2/100000ths of P, the heat exchanger of average 1000 groups of 100 passages of soldering by what do not add P, only have two solder joints to need repair welding, slip has reduced 66.7%(referring to table 1).
Three, " cooperative effect " of alterant element Sr and Si, Ti, Ni, P found in research.
There are some researches show, in Al-Si alloy, add the elements such as Sr, the particularly reciprocation of Sr and B, Sr and Ti, existing a large amount of bibliographical information.But, Zn content, up to 36.0% ~ 65.0% solder of the present invention, obviously has marked difference with the character of Al-Si alloy, adopts method and element " rotten processing " poor effect of existing bibliographical information.Therefore, the present invention is in test, research process, find adding on the basis of Sr and Si, Ti, add again Ni, P element, in the time having Ni, P element and Sr and Si, Ti to coexist, the tool bubble-tight effect that increases significantly, and solder wetting, permeability, brazed seam mechanical property are not had to " negative Effect.By adopting " sequential experiment design " method to carry out further " preferably " to Sr, Si, Ti, Ni, P, obtain the composition range of this claim 1.Adopt oxy-propane flame brazing mode soldering 3003 aluminium-alloy pipes-tubular construction (socket), use " flux-cored wire " or brazing wire to coordinate CsF-AlF
3brazing flux, soldered fitting is through the water pressure test (hydraulic pressure is 18MPa, pressurize 30 minutes), brazed seam is without leakage.Soldered fitting maximum in the water pressure test is born pressure can reach 21 MPa(at aluminum pipe position cracking).
